In a position lower than the substrate carrying mechanism 10 for the coater COT block COTB is disposed the substrate carrying mechanism 10, not shown, for the first development processing apparatus DEV block DEVB.

In addition, a plurality of arms is set for carrying in and carrying out of the semiconductor wafer W to/from a predetermined processing apparatus, and configured to improve throughput according to transport of the semiconductor wafer W.

In a position lower than the substrate carrying mechanism 10 for the first development processing apparatus DEV block DEVB is disposed the substrate carrying mechanism 10, not shown, for the second development processing apparatus DEV block DEVB. A travel region in the vertical direction of the substrate carrying mechanism 10 is configured to correspond to the development processing apparatus DEV block DEVB, have the same length as the vertical length of the development processing apparatus DEV block DEVB, and enable the mechanism 10 to carry the semiconductor wafer W to the development processing apparatuses DEV in the region of the development processing apparatus DEV block DEVB and heaters HPB4 and COLB4.

The substrate delivering/receiving stations 20 and 21 are configured to be movable in the Z direction (vertical direction) to be able to deliver and receive the semiconductor wafer W to/from each of the substrate delivering/receiving mechanisms 10.

In this embodiment, the substrate carrying mechanism 10 for the second development processing apparatus DEV block DEVB is provided in the position lower than the substrate carrying mechanism 10 for the first development processing apparatus DEV block DEVB. Alternately, since the development processing apparatus DEV blocks DEVBs are a processing group that performs the same processing, instead of providing two substrate carrying mechanisms 10 for the first and second development processing apparatus DEV blocks DEVBs, a single substrate carrying mechanism 10 may support the first and second development processing apparatus DEV blocks DEVBs. In this case, the heaters as shown in FIG. 3 in the order of HPB3→COLB3→HPB4→COLB4, from the top to bottom, may be changed to the order of HPB3→HPB4→COLB3→COLB4, from the top to bottom.

However, when any limitations and the like are not imposed on the height of the apparatus, the vertical length of the first development processing apparatus DEV block DEVB may be substantially the same as the vertical length of the antireflective film forming apparatus HB block HBB.

In addition, the arm 11 of each substrate carrying mechanism 10 is configured to carry the semiconductor wafer W freely to/from the heater and liquid processing apparatus as described previously via a carrying in/out opening 16 which is provided in each of the heaters and liquid processing apparatuses and configured to be openable and closable. In addition, the carrying in/out opening 16 is provided with an opening/closing mechanism not shown, for example, a shutter, and each carrying in/out opening 16 is configured to be openable and closable independently by the shutter. Further, the substrate delivering/receiving stations 20 and 21 are configured to be managed by a temperature adjustment mechanism that adjusts the temperature of the semiconductor wafer W to a predetermined temperature, for example, substantially 23° C. as room temperature.

As shown in FIG. 5, the substrate carrying in/out mechanism 2 in the cassette unit section CU is configured to be self-propelled in the X direction (X axis), and is provided with an arm 45 configured to be movable in the vertical direction (Z axis), extendable direction (Y axis) and rotation direction (θ axis). Further, a wall 46 is disposed between the cassette unit section CU and process unit section PU, configured to interrupt the atmosphere between the space inside the cassette unit section CU and the space inside the process unit section PU, and provided with an opening 47 of the substrate delivering/receiving section 8, as shown in FIG. 6. The opening 47 is configured to be openable and closable by an opening/closing mechanism not shown, for example, a shutter.

A height position h5 of the opening 47 is set at a position higher than a height position h4 where a cassette C is mounted. Further, the opening 47 is disposed in a position higher than a height position of the arm 45 when the arm 45 of the substrate carrying in/out mechanism 2 travels in the X direction (the longitudinal direction of the cassette unit section CU). The relationship of the height position is that the height position h5 of the opening 47>height position of the arm 45 of the substrate carrying in/out mechanism 2 when the arm 45 travels in the X direction>height position h4 where the cassette C is mounted. By this means, it is possible to prevent the mist and like from the substrate carrying in/out mechanism 2 from entering the process unit section PU side. In addition, above the cassette unit section CU is provided a gas introducing mechanism not shown to flow downward a gas such as clean air and the like toward the cassette unit section CU.

The substrate delivering/receiving section 8 of the process unit section PU is provided with a plurality of support mechanisms, for example, support pins 50 configured to be movable up and down to deliver and receive the semiconductor wafer W, and to be able to deliver and receive the semiconductor wafer W to/from the substrate carrying in/out mechanism 2 or substrate carrying mechanism 10. Further, in a position above the substrate delivering/receiving section 8 is disposed a heater 51 that performs heat treatment on the semiconductor wafer W with a first predetermined temperature. Between the heater 51 and substrate delivering/receiving section 8 is disposed a heater 52 that performs heat treatment on the semiconductor wafer W with a second predetermined temperature lower than the first temperature. In a position under the substrate delivering/receiving section 8 is disposed a plurality of temperature adjustment mechanisms 53 to adjust (cool) the temperature of the semiconductor wafer W treated in the heaters 51 and 52 to a predetermined temperature, for example, the temperature substantially the same as the ambient temperature inside the process unit section PU, for example, the temperature of substantially 23° C.

In addition, the substrate carrying mechanism TR1 carries the semiconductor wafer W to/from the temperature adjustment mechanisms 53 and heaters 51 and 52, while the substrate carrying in/out mechanism 2 is configured not to be able to access the mechanisms 53 and heaters 51 and 52. Further, openings 54 on the process unit section PU side of the substrate delivering/receiving section 8, temperature adjustment mechanisms 53 and heaters 51 and 52 are configured to be openable and closable by an opening/closing mechanism not shown, for example, a shutter. A filter section not shown is provided above each of the substrate carrying in/out mechanism section U2 of the cassette unit section CU, process unit section PU and interface unit section IFU, and configured to supply the temperature/humidity air with the temperature and humidity of respective set values to each of the units. The temperature/humidity air is configured to be set at a predetermined amount by each exhaust setting mechanism to be recovered from an exhaust hole provided under each unit, and it is thus configured that a down-flow of the temperature/humidity air is formed inside each unit.

Further, the pressure of each of the substrate carrying in/out mechanism section U2 of the cassette unit section CU, process unit section PU and interface unit section IFU is set by the exhaust setting mechanism thereof so that the pressure of the process unit section PU is set to be higher than both the pressure of the substrate carrying in/out mechanism section U2 of the cassette unit section CU, and the pressure of the interface unit section IFU, and that the pressure inside the exposure apparatus 3 is set to be higher than the pressure of the interface unit section IFU. It is thus configured to prevent unnecessary mist from entering the process unit section PU or exposure apparatus 3 to be a factor having an adverse effect on the processing of the semiconductor wafer W. Further, as compared with the level of oxygen and/or acid gas (NOX, SOX, H₂S, CO₂ and the like), base gas (ammonia, amine and the like), and/or moisture contained in the atmosphere of the cassette unit section CU, the level contained in the atmosphere of the process unit section PU and/or interface unit section IFU is substantially set to be lower than the level of the section CU. This is because of improving the yield of the processing of the semiconductor wafer by reducing effects of the gases particularly in the processing prior or subsequent to exposure.

As shown in FIG. 7, the substrate carrying in/out mechanism 6 in the interface unit section IFU is configured to be self-propelled movable in the X direction (X axis), and provided with an arm 55 configured to be movable in the vertical direction (Z axis), extendable direction (Y axis) and rotation direction (θ axis). Further, a wall 56 is provided between the interface unit section IFU and process unit section PU, configured to interrupt the atmosphere between the space inside the interface unit section IFU and the space inside the process unit section PU, and provided with an opening 57 of the substrate delivering/receiving section 9. The opening 57 is configured to be openable and closable by an opening/closing mechanism not shown, for example, a shutter.

A height position h6 of the opening 57 is set at a position lower than a height position h7 of an opening 58 of a heating processing chamber FH. Further, the opening 57 is disposed in a position higher than a height position of the arm 55 when the arm 55 of the substrate carrying in/out mechanism 6 travels in the X direction (the longitudinal direction of the interface unit section IFU). The relationship of the height position is that the height position h6 of the opening 57>height position of the arm 55 of the substrate carrying in/out mechanism 6 when the arm 55 travels in the X direction>height position h7 of the opening 58 of the heating processing chamber FH. It is thus configured to prevent the heat from the heating processing chamber FH and/or mist from the heating processing chamber FH and/or substrate carrying in/out mechanism 2 and like from entering the process unit section PU side. In addition, the height position h6 of the opening 57 is set to be substantially the same as the height position h5 of the opening 47, and thus configured to improve the efficiency of carrying by the substrate carrying mechanism 10. In addition, under and above the substrate delivering/receiving section 9 are disposed the heaters or temperature adjustment apparatuses configured to be stacked in the same way as in the substrate delivering/receiving section 8.

As shown in FIG. 8, the heating processing chamber FH is provided with a rectangular temperature adjustment mechanism 60 that adjusts (cools) the temperature of the semiconductor wafer W to a predetermined temperature, for example, the ambient temperature inside the interface unit section IFU, for example, to substantially 23° C., and a heating mechanism 61 that performs post exposure baking (PEB) on the semiconductor wafer W subjected to the exposure processing in the exposure apparatus 3 at a predetermined temperature. The temperature adjustment mechanism 60 is configured to be movable in the X direction (X axis), and moving up/down mechanisms 62 are provided under the temperature adjustment mechanism 60 in the home position of the mechanism 60 and in a position lower than the heating mechanism 61 to be configured to be able to deliver and receive the semiconductor wafer W to/from the temperature adjustment mechanism 60 and heating mechanism 61, respectively. Each of the moving up/down mechanisms 62 has a plurality of support mechanisms, for example, support pins 64 on a base 63, and is configured to be able to support the semiconductor wafer W from the backside in point contact by the support pins 64.

The temperature adjustment mechanism 60 is further provided with notches 65 not in contact with the support pins 64 of the moving up/down mechanism 62 on the heating mechanism 61 side, and configured to travel to a position above the heating mechanism 61 to be able to deliver and receive the semiconductor wafer W using the support pins 64 of the moving up/down mechanism 62 on the heating mechanism 61 side. In addition, the opening 58 is provided in the X direction (the longitudinal direction of the heating processing chamber FH), and is configured to be openable and closable by an opening/closing mechanism not shown, for example, a shutter. The moving up/down mechanism 62 on the temperature adjustment mechanism 60 side is configured to be able to deliver and receive the semiconductor wafer W to/from the arm 55 of the substrate carrying in/out mechanism 6, as well as delivering and receiving the wafer W to/from the temperature adjustment mechanism 60.

As shown in FIG. 9, each of the heaters HP1 to HP4 and the like of the heater HP blocks HPB1 to HPB4 has substantially the same configuration as that of the heating processing chamber FH, and is provided with a rectangular temperature adjustment mechanism 70 that adjusts (cools) the temperature of the semiconductor wafer W to a predetermined temperature, for example, the ambient temperature inside the process unit section PU, for example, to substantially 23° C., and a heating mechanism 71 that heats and treats the semiconductor wafer W at a predetermined temperature. The temperature adjustment mechanism 70 is configured to be movable in the Y direction, and moving up/down mechanisms not shown are provided under the temperature adjustment mechanism 70 in the home position of the mechanism 70 and in a position lower than the heating mechanism 71 and configured to be able to deliver and receive the semiconductor wafer W to/from the temperature adjustment mechanism 70 and heating mechanism 71, respectively. Each of the moving up/down mechanisms has a plurality of support mechanisms, for example, support pins and is configured to be able to support the semiconductor wafer W from the backside in point contact by the support pins.

The temperature adjustment mechanism 70 is further provided with notches 72 not in contact with the support pins of the moving up/down mechanism on the heating mechanism 71 side, and configured to travel to a position above the heating mechanism 71 to be able to deliver and receive the semiconductor wafer W using the support pins of the moving up/down mechanism on the heating mechanism 71 side. In addition, the opening 16 of each of the heaters HP1 to HP4 is provided in the Y direction (the longitudinal direction of the heating processing chamber FH), and is configured to be openable and closable by an opening/closing mechanism not shown, for example, a shutter. The moving up/down mechanism on the temperature adjustment mechanism 70 side is configured to be able to deliver and receive the semiconductor wafer W to/from the arm 11 of the substrate carrying mechanism 10, as well as delivering and receiving the wafer W to/from the temperature adjustment mechanism 70.

Further, as shown in FIG. l0, each temperature adjustment mechanism 70 is provided with a flowing path 78 to flow a cooling medium, for example, cooling water to set the temperature adjustment mechanism 70 at a predetermined temperature, for example, substantially 23° C. The flowing path 78 is configured to supply the cooling water from a cooling medium supply mechanism 81 via a pipe 82. For example, it is configured that the cooling water supplied to the temperature adjustment mechanism 70 of the heater HP4 from the cooling medium supply mechanism 81 as the cooling liquid supply mechanism is supplied to the flowing path 78 of the temperature adjustment mechanism 70 of a subsequent-stage heater, for example, heater HP3 by a connection pipe 79 via the flowing path 78, the cooling water supplied to the temperature adjustment mechanism 70 of the heater HP3 is supplied to the flowing path 78 of the temperature adjustment mechanism 70 of a subsequent-stage heater, for example, heater HP2 by the connection pipe 79 via the flowing path 78, and that the cooling water supplied to the temperature adjustment mechanism 70 of the heater HP2 is supplied to the flowing path 78 of the temperature adjustment mechanism 70 of a subsequent-stage heater, for example, heater HP1 by the connection pipe 79 via the flowing path 78.

Further, the cooling water from the flowing path 78 of the temperature adjustment mechanism 70 of the heater HP1 is returned to a cooling medium recovery mechanism 82 via a pipe 80 that collects the cooling medium. In addition, it is configured in this embodiment that the cooling water flows from the heater HP4 side to the heater HP1 side, but the flow of the cooling water can be set as appropriate. Further, as shown in FIG. 11, it is configured that the cooling medium supply mechanism 81 and cooling medium recovery mechanism 82 are managed on a basis of a horizontal block of the heaters, and that cooling water ports 90 (for the heater block HPB1) and 91 (for the heater block HPB2) in each of which the cooling medium supply mechanism 81 and cooling medium recovery mechanism 82 are arranged are disposed for heaters HPB1 to HPB4. In addition, not shown in FIG. 11, the cooling water port for the heater block HPB3 is “92” as shown in FIG. 12, and the cooling water port for the heater block HPB4 is “93” as shown in FIG. 12.

As shown in FIGS. 12 and 13, the cooling water ports 90 to 93 are disposed in predetermined positions of the process unit section PU. The cooling water ports 90 to 93 are configured to be connected to a utility apparatus disposed outside the apparatus, for example, a cooling medium utility apparatus 100 via respective pipes 101 corresponding to the cooling water ports 90 to 93. The cooling medium utility apparatus 100 is provided with ports 90 a to 93 a corresponding to the cooling water ports 90 to 93. Further, the cooling medium utility apparatus 100 is provided with a water introduction port 106 that takes in the water for cooling water from the outside of the cooling medium utility device 100, and with a water discharge port 107 that discharges the cooling water used in the substrate processing apparatus 1 from the ports 90 a to 93 a.

Further, the cooling medium utility apparatus 100 is provided with at least one temperature adjustment mechanism, for example, temperature adjustment mechanisms 102 and 103 to set the water as a cooling medium introduced from the water introducing port 106 at a predetermined temperature used in the substrate processing apparatus, for example, at substantially 23° C., by instructions from a control mechanism 105. The cooling water set for the predetermined temperature by the temperature adjustment mechanisms 102 and 103 is configured to enable switching to select between switching mechanisms, for example, a switching mechanism SW1 route and switching mechanism SW2 route each comprised of a valve and the like, by instructions from the control mechanism 105, and to be sent from the temperature adjustment mechanism 102 or 103 collectively to the substrate processing apparatus 1 from respective OUT sides via the ports 90 a to 93 a. In addition, in this embodiment, a plurality of temperature adjustment mechanisms, i.e. two temperature adjustment mechanisms, 102 and 103, are provided, but naturally, one temperature adjustment mechanism may support the apparatus.

Described next is another embodiment of the cooling medium supply mechanism 81 and cooling medium recovery mechanism 82 described previously. As shown in FIG. 14, the cooling water supplied from the cooling medium supply mechanism 81 is configured to be once branched to a plurality of flows by a branch mechanism 99, and supplied to the temperature adjustment mechanism of each heater of the horizontal block of the heaters. Further, the cooling water recovered from the temperature adjustment mechanism of each heater is configured to be collectively recovered to the cooling medium recovery mechanism 82. Thus, the cooling water is supplied independently via each supply line to the temperature adjustment mechanism of each heater, and it is thus possible to provide the apparatus with a higher level of safety.

Described next is the switching between the switching mechanisms SW1 and SW2. It is assumed that the cooling water is first sent from the OUT side of each of the ports 90 a to 93 a to the substrate processing apparatus 1 via the switching mechanism SW1 route. The cooling water flows for each horizontal block of heaters, i.e. flows into the heaters HPB1 to HPB4, and recovered to the IN side of each of the ports 90 a to 93 a for each horizontal block. The IN side of each of the ports 90 a to 93 a of the recovered cooling water is provided with a temperature detecting mechanism that detects the temperature of the recovered cooling water for each of the ports 90 a to 93 a. The information of the temperature detecting mechanisms is managed by the control mechanism 105, and it is configured that when at least one of respective temperature detecting mechanisms of the IN sides of the ports 90 a to 93 a detects a value outside set range values, the control mechanism 105 switches from the switching mechanism SW1 route to the switching mechanism SW2 route, while transmitting a first abnormal signal to a control mechanism of the substrate processing side to report the information. Thus, the cooling water is managed for each horizontal block of the heaters.

In addition, the temperature adjustments mechanisms may not be particularly provided on the OUT sides of the ports 90 a to 93 a of the cooling water. This is because the temperature of the sent cooling water is managed by the temperature adjustments mechanisms 102 and 103. Further, when the detecting mechanism detects a value outside the set range values also after switching to the switching mechanism SW2 route, the recovery line falling outside the set range temperature values among the IN sides of the ports 90 a to 93 a is configured to transmit a second abnormal signal to the control mechanism of the substrate processing apparatus 1 side to report the information. The temperature of the temperature adjustment mechanism 70 of each heater HP is configured to be detected by a temperature detecting mechanism, but it is not clear on whether the cooling medium utility apparatus 100 has the problem or the temperature adjustment mechanism 70 of each heater HP has the problem. Therefore, the control mechanism of the substrate processing apparatus 1 side is configured to judge the abnormal condition based on the information of the temperature detecting mechanism of the temperature adjustment mechanism 70 of each heater HP and the above-mentioned first and/or second abnormal signal to be able to identify a location of the problem. It is thus configured to greatly improve the safety of the apparatus itself by management of the horizontal block and the dedicated temperature detecting mechanism of the temperature adjustment mechanism 70 of each heater.

Further, for utility, for example, supply of a gas with adjusted predetermined temperature and humidity to each of liquid processing apparatuses of each of horizontal blocks HBB, COTB, DEVB1 and DEVB2, as shown in FIG. 15, it is configured that a utility apparatus disposed outside the substrate processing apparatus 1, for example, a gas utility apparatus 120 that supplies the gas with adjusted predetermined temperature and humidity sends the gas to ports WPFP1 to WPFP4 provided in predetermined positions of the substrate processing apparatus 1 independently through a number of lines corresponding to the number horizontal blocks HBB, COTB, DEVB1 and DEVB2, in this case, through four lines via ports W1 to W4 of the gas utility apparatus 120. Further, by gas branch mechanisms WPF1 to WPF4, the gas sent to the ports WPFP1 to WPFP4 is configured to be supplied to each liquid processing apparatus of each liquid processing apparatus horizontal block via an independent pipe 110, respectively.

Furthermore, as shown in FIG. 16, in the gas utility apparatus 120, the ports W1 to W4 are provided in an upper position of the apparatus 120. The reason of such installation is that the footprint of the apparatus can be decreased. Further, the gas utility apparatus 120 is configured to take a gas prior to adjustments of the temperature and humidity inside the apparatus from outside the apparatus through a gas introducing portion 122 via a filter 121. The gas taken in through the gas introducing portion 122 is taken in a cooling portion 123 as the first space portion, and it is configured that cooling plates 126 each in a predetermined shape, for example, in the shape of a rectangle, provided in a cooling medium flowing pipe 125, are cooled by a cooling medium flowing through the cooling medium flowing pipe 125 of a cooing medium supply mechanism 124 and that the introduced gas can be cooled. Further, in a position above the cooling plates 126 is provided an introducing portion 128 as a path (flowing portion) to introduce the gas cooled by the cooling plates 126 to a second space portion 127.

In addition, for the relationship between the introducing portion 128 and cooling plates 126, as shown in FIG. 17, it is configured that the introducing portion 128 is disposed in part of the region of the cooling plates 126, for example, in the region of one end, and that the height of the cooling plates 126 b disposed in positions under the introducing portion 128 extends to a position higher than the height of cooling plates 126 a in positions except the positions immediately under the introducing portion 128. This is because of the effects of cooling the gas in the entire region of the cooling portion 123, and sending the cooled gas to be sent to the introducing portion 128 to the vicinity of the introducing portion 128 without changing the temperature of the cooled gas. Further, for connection between a plurality of cooling plates 126 and cooling medium flowing pipe 125, it is preferable that the plurality of cooling plates 126 is inserted in the cooling medium flowing pipe 125 to be fixed, and thus is attached to be detachable, instead of being fixed by welding and the like. The reason is, particularly, because it is required to adjust a flow of the gas and the adjustments can be facilitated. Accordingly, intervals of the plurality of cooling plates 126 are configured to be varied easily. In addition, for the plurality of cooling plates 126, it is shown in FIG. 16 that a plurality of rectangular plates is arranged from the gas introducing portion 122 side to the cooling medium supply mechanism 124 side, but as shown in FIG. 17, the plurality of cooling plates 126 may be arranged in parallel from the back to the front, as viewed in the figure.

Above the introducing portion 128 on the second space portion 127 side, for example, immediately above the portion 128 is disposed a heating mechanism, for example, a heater 129 to heat the cooled gas flowing from the cooling portion 123 through the introducing portion 128 to a predetermined temperature, for example, substantially 23° C. To the side of the heater 129 is disposed a blowing mechanism 130 that sends the gas of the space portion 127 to the substrate processing apparatus 1 via the ports W1 to W4. A center height position CP of a rotation mechanism of the blowing mechanism 130, for example, of a rotation fan 131 is configured to be higher than an installation position of the heater 129 to improve the efficiency in sending the wind. Further, in the second space portion 127, not shown in the figure, a humidity adjustment mechanism is provided to set the gas inside the space portion 127 at a predetermined humidity. A control mechanism 135 of the gas utility apparatus 120 is provided on the side opposite to the filter 121 of the apparatus 120, and configured to control the heater 129, cooling medium supply mechanism 124 and blowing mechanism 130 described above.

The gas utility apparatus 120 supplies the gas with adjusted temperature and humidity to each of the antireflective film forming apparatuses HB, coaters COT and development processing apparatuses DEV via the pipe 110, as described above. For the configuration of the antireflective film forming apparatus HB and/or coater COT, as shown in FIG. 18, the apparatus HB and/or coater COT is provided inside the apparatus with a rotation member 140 that holds the semiconductor wafer W to rotate, and a cup 141 surrounding the rotation member 140. Above the cup 141 is provided a gas supply apparatus 142 having a width H9 in the vertical direction to send the gas supplied from the pipe 110 to the direction of the cup 141. Further, the gas supply apparatus 142 has rectifying mechanisms 143 that send the down-flow with high accuracy. Furthermore, the distance between the gas supply apparatus 142 and the position of the upper face of the cup 141 is set at a distance of H10.

For the configuration of the development processing apparatus DEV, as shown in FIG. 19, the apparatus DEV is provided inside the apparatus with the rotation member 140 that holds the semiconductor wafer W to rotate, and the cup 141 surrounding the rotation member 140. Above the cup 141 is provided a gas supply apparatus 144 having a width H9 in the vertical direction to send the gas supplied from the pipe 110 to the direction of the cup 141. The gas supply apparatus may have rectifying mechanisms, but a lower degree of accuracy than that of the antireflective film forming apparatus HB and coater COT is enough, and the rectifying mechanisms are not required particularly. It is thus possible to limit the vertical length of the development processing apparatus DEV to a length smaller than the vertical length of the antireflective film forming apparatus HB and/or coater COT. Accordingly, the vertical length of the gas supply apparatus 144 is configured to be smaller than the vertical length of the gas supply apparatus 142. Further, the distance h12 between the gas supply apparatus 144 and the position of the upper face of the cup 141 is set at a distance smaller than the distance h10 described above.

For utility to each liquid processing apparatus of each of the horizontal blocks HBB, COTB, DEVB1 and DEVB2 of respective liquid processing apparatuses, a utility apparatus disposed outside the substrate processing apparatus 1 supplies each utility. As shown in FIG. 20, for the HBB and COTB, a utility apparatus 170 supplies a predetermined processing liquid, for example, resist solution, and an inert gas, for example, N₂. For the DEVBs, a utility apparatus 171 supplies a predetermined processing liquid, for example, developing solution, and pure water and the like. Described first is about the horizontal blocks HBB and COTB. The utility apparatus 170 as a COT chemical cabinet sends utility set for a predetermined temperature, for example, a processing liquid, for example, a resist solution (as the utility, the gas, for example, N₂ is in the same configuration, and descriptions thereof are omitted) to ports PC1 a and PC2 a on the substrate processing apparatus 1 side from ports PC1 and PC2, respectively. It is configured that branch mechanisms PC1 b and PC2 b each comprised of a valve and the like on the substrate processing apparatus 1 side are capable of supplying the utility from the ports PC1 a and PC2 a to each liquid processing chamber of the horizontal blocks HBB and COTB, respectively.

Described next is about the horizontal blocks HBBs. The utility apparatus 171 as a DEV chemical cabinet sends utility set for a predetermined temperature, for example, a processing liquid, for example, a developing solution (as the utility, another processing liquid, for example, pure water is in the same configuration, and descriptions thereof are omitted) to ports PD1 a and PD2 a on the substrate processing apparatus 1 side from ports PD1 and PD2, respectively. It is configured that branch mechanisms PD1 b and PD2 b each comprised of a valve and the like on the substrate processing apparatus 1 side are capable of supplying the utility from the ports PD1 a and PD2 a to each liquid processing chamber of the horizontal blocks DEVBs, respectively.

For supply of utility, for example, a predetermined processing gas, for example, a gas such as HMDS and the like, to each AD of the horizontal block ADB of ADs of the heaters, as shown in FIG. 21, the utility apparatus 170 disposed outside the substrate processing apparatus 1 as the COT chemical cabinet is configured to be shared with the above-mentioned configuration. The utility apparatus 170 sends the utility set for a predetermined temperature, for example, the gas such as HMDS and the like to a port PC3 a on the substrate processing apparatus 1 side from a port PC3. A branch mechanism PC3 b comprised of a valve and the like on the substrate processing apparatus 1 side is configured to be able to supply the utility from the port PC3 a to each heater of the horizontal block ADB of heaters ADs. Further, the substrate processing apparatus 1 is provided with a control mechanism 180 and further with a main operation mechanism 181 and sub-operation mechanism 182. The utility apparatus 170 has a control mechanism 183 and operation mechanism 184, and the control mechanisms 183 and 180 are configured to convey information via a communication line 185 as communication means. The sub-operation mechanism 182 and operation mechanism 184 are configured to perform the same operation in predetermined operation. The same operation is operation used in performing maintenance such as dummy dispense, step control and the like. In addition, another external utility apparatus may have such an operation mechanism, but it is preferable that the substrate processing apparatus 1 and utility apparatus 170 as the COT chemical cabinet only have at least such a function.

Described next is the processing operation of the resist processing apparatus 1 configured as described above. First, a worker or cassette carrying robot places a cassette C storing a plurality of unprocessed semiconductor wafers W in a cassette mount section U1 of the cassette unit section CU. Then, the substrate carrying in/out mechanism 2 of the substrate carrying in/out mechanism section U2 carries the semiconductor wafers W out of the cassette C on a sheet basis, once adjusts the position of the semiconductor wafer W, and delivers the semiconductor wafer W to the substrate delivering/receiving section 8 of the process unit section PU.

Then, the semiconductor wafer W is carried to the substrate delivering/receiving station 20 from the substrate delivering/receiving section 8 by the substrate carrying mechanism TR1. Subsequently, the substrate delivering/receiving station 20 travels to a predetermined height position of the horizontal block HBB region in the vertical direction, and the semiconductor wafer W is carried to a predetermined AD section in the heater section by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, and undergoes hydrophobic processing in the AD section. Then, the semiconductor wafer W is carried from the AD section to the heater HP in the horizontal block HBB region by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, further carried to the heating processing mechanism 61 via the temperature adjustment mechanism 60 of the heater HP, and processed at a predetermined temperature. The semiconductor wafer W subjected to the heating processing in the heating processing mechanism 61 is adjusted in temperature to a predetermined temperature, substantially 23° C. by the temperature adjustment mechanism 60, and carried from the heater HP by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region.

Further, the semiconductor wafer W is carried to a predetermined temperature adjustment section COL in the horizontal block HBB by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, and adjusted in temperature to a predetermined temperature, substantially 23° C. Then, the semiconductor wafer W is carried from the temperature adjustment section COL by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, and moved to the direction of the liquid processing apparatus in the horizontal block HBB by the substrate carrying mechanism 10 rotating. Subsequently, the semiconductor wafer W is carried to a predetermined liquid processing apparatus HB, and an antireflective film is formed on the processing surface of the semiconductor wafer W. Then, the semiconductor wafer W is carried from the liquid processing apparatus HB by the arm 11 of the substrate carrying mechanism 10, carried to a heater HP of the heater section by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, further carried to the heating processing mechanism 61 via the temperature adjustment mechanism 60 of the heater HP, and processed at a predetermined temperature.

The semiconductor wafer W subjected to the heating processing in the heating processing mechanism 61 is adjusted in temperature to a predetermined temperature, substantially 23° C. by the temperature adjustment mechanism 60, and carried from the heater HP by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region. Further, the semiconductor wafer W is carried to a predetermined temperature adjustment section COL in the horizontal block HBB region by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, and adjusted in temperature to a predetermined temperature, substantially 23° C. Then, the semiconductor wafer W is carried from the temperature adjustment section COL by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region, and carried to the substrate delivering/receiving station 20 or 21 by the substrate carrying mechanism 10.

The substrate delivering/receiving station 20 or 21 travels to a lower position, halts in a delivering position for the arm 11 of the substrate carrying mechanism 10 in the horizontal block COT region, and delivers the semiconductor wafer W to the arm 11 of the substrate carrying mechanism 10 in the horizontal block COT region. In the horizontal block COT region, the processing steps are performed as in the processing in the HBB, but the processing steps for AD may be selected as appropriate when necessary. The semiconductor wafer with the processing in the horizontal block COT region finished is carried to the substrate delivering/receiving station 21 and carried to the substrate delivering/receiving section 9 by the substrate carrying mechanism TR2. The semiconductor wafer W is delivered to the interface unit section IFU via the substrate delivering/receiving section 9, further delivered to the exposure apparatus 3 via the substrate carrying in/out mechanism 6 from the interface unit section IFU, and subjected to the exposure processing.

The exposure-processed semiconductor wafer W is delivered to the interface unit section IFU, and then, carried to the heating processing mechanism FH by the substrate carrying in/out mechanism 6. In the heating processing mechanism FH, the semiconductor wafer W is delivered to the temperature adjustment mechanism 60 of the heating processing mechanism FH, and undergoes heat treatment at a predetermined temperature e.g. a first temperature in the heating mechanism 61. Then, the semiconductor wafer W is delivered to the temperature adjustment mechanism 60 from the heating mechanism 61, and after the temperature of the semiconductor wafer W reaches a predetermined temperature in the temperature adjustment mechanism 60, carried to the substrate delivering/receiving section 9 by the substrate carrying in/out mechanism 6. The reason why the heating processing mechanism FH is thus disposed in the interface unit section IFU is because of controlling the time the exposure processing is performed in the exposure apparatus 3 and making the time between the exposure processing in the exposure apparatus 3 and heat treatment constant in each processing target substrate. By this means, the yield of processing target substrates is enhanced.

Then, the semiconductor wafer W is carried to the substrate delivering/receiving station 21 by the substrate carrying mechanism TR2 via the substrate delivering/receiving section 9. Subsequently, the substrate delivering/receiving station 21 travels to a predetermined height position of the horizontal block DEVB region in the vertical direction, the semiconductor wafer W is carried to a predetermined liquid processing apparatus DEV in the heater section by the arm 11 of the substrate carrying mechanism 10 in the horizontal block DEVB region, and development processing is performed on the resist film formed on the processing surface of the semiconductor wafer W. Then, the semiconductor wafer W is carried from the liquid processing apparatus DEV by the arm 11 of the substrate carrying mechanism 10, carried to the heater HP in heater section by the arm 11 of the substrate carrying mechanism 10 in the horizontal block DEVB region, further carried to the heating processing mechanism 61 via the temperature adjustment mechanism 60 of the heater HP, and processed at a predetermined temperature.

The semiconductor wafer W subjected to the heating processing in the heating processing mechanism 61 is adjusted in temperature to a predetermined temperature, substantially 23° C. by the temperature adjustment mechanism 60, and carried from the heater HP by the arm 11 of the substrate carrying mechanism 10 in the horizontal block HBB region.

In addition, the same components as in the above-mentioned embodiments are assigned the same reference numerals to omit specific descriptions. Naturally, the invention according to this embodiment is capable of being used in a combination with another embodiment, and is not limited to this embodiment.

Each block of the antireflective film forming apparatus HBB, coater COTB and development processing apparatus DEVB as the liquid processing apparatuses described previously is provided with respective liquid processing apparatuses, i.e. respectively with a plurality of antireflective film forming apparatuses HB, coaters COT and development processing apparatuses DEV.

In the foregoing, the antireflective film forming apparatus HBB includes a plurality of antireflective film forming apparatuses HB disposed horizontally, and the atmosphere inside each antireflective film forming apparatus HB is provided independently, but the atmosphere inside each antireflective film forming apparatus HB is shared. Cups 141 are disposed in a line horizontally. A common gas supply mechanism 142 is provided in a position above the cups 141, but the gas supply mechanism 142 may be provided independently as in the foregoing. By such a configuration, distances corresponding to processing walls of liquid processing apparatuses can be eliminated, and it is thus possible to decrease the footprint as a liquid processing block, and to reduce the size of the system.

Further, each block of the antireflective film forming apparatus HBB, coater COTB and development processing apparatus DEVB as the liquid processing apparatuses described previously is provided with respective liquid processing apparatuses, i.e. respectively with a plurality of antireflective film forming apparatuses HB, coaters COT and development processing apparatuses DEV, and in each liquid processing chamber are provided a nozzle that supplies the processing liquid, and a nozzle moving mechanism that moves the nozzle to above the semiconductor wafer W inside the cup. As shown in FIG. 24, when a plurality of cups 141 exists in the same space, it is configured that a single nozzle moving mechanism 202 travels in the direction parallel with the arrangement direction of the cups 141 to supply the processing liquid to the semiconductor wafer W inside each of the cups 141. Further, an arm 203 of the nozzle moving mechanism 202 is provided with a nozzle holding mechanism that holds a nozzle 201 selected as appropriate from a nozzle arrangement region 200 which is disposed in the same atmosphere inside the liquid processing apparatus and in which a plurality of nozzles 201 is linearly arranged. By such a configuration, since the need is eliminated of providing each liquid processing apparatus with the nozzle moving mechanism independently, as well as downsizing of the system, it is possible to reduce the cost of the system and improve the safety of the apparatus.

Described next is another embodiment in blocks of the antireflective film forming apparatus HB, coater COT and development processing apparatus DEV as liquid processing apparatuses and heaters HPB, ADB and COLB of this embodiment.

Each utility apparatus as described previously supplies each utility on a horizontal block basis to the antireflective film forming apparatus HBB, coater COTB and development processing apparatus DEVB as liquid processing apparatuses as described previously and heater blocks of heaters HPB, ADB and COLB. In an apparatus where each of the antireflective film forming apparatus HBB, coater COTB and development processing apparatus DEVB, and heater blocks of heaters HPB, ADB and COLB constitutes the same type of processing apparatuses as a vertical block, instead of a horizontal block, the techniques described in the invention are naturally applied on a vertical block basis, instead of a horizontal block basis. Further, the invention is also applicable to the case where a plurality of block is configured in the form of a rectangle, for example, as four blocks.

Then, it is configured that the gas is introduced to a third space portion 211 on the operation mechanism side of the control mechanism 135 by a fan as the rotation fan 131. It is further configured that the gas is adjusted in the third space portion 211 by a humidity adjustment mechanism not shown that adjusts the gas to a predetermined humidity, and introduced to a fourth space portion 212 via an opening portion 213. Thus, provided are the first space portion 123 as a gas cooling section, the second space portion 219 as a gas heating section, the third space portion 211 as a gas humidifying section and the fourth space portion 212 as a section to exhaust the gas to another apparatus, and it is thereby possible to efficiently control the temperature, humidity and total exhaust amount. Further, since the second space portion 219 and third space portion 211 are disposed in substantially horizontal positions, it is possible to achieve a reduction in size of the apparatus itself. The gas exhausted from the fourth space portion 212 may be used as the down-flow in the interface unit section IFU of the resist processing apparatus 1.
